Administrator password (also valid for Mitel SIP phones) |
Here you can set the local password for all connected IP system phones and Mitel SIP phones at the same time. Any passwords already set are then overwritten. You must restart Mitel SIP phones to activate the new password. The password is immediately activated on IP system phones. To assign the passwords locally to the phones, the entry must be blank. A phone first-start has to be carried out to reset the password to the default values. The default administrator password for IP system phones is “0000”. The default administrator password for Mitel SIP phones is “22222”. |

|
Layer 2: VLAN-ID |
ID of the VLAN to which the communication server should be assigned. Note:
If the IP phones are also included in the VLAN (Active for = Nodes and Terminals setting), then the IP phones must be assigned to the same VLAN. |

Note:
Layer 2 settings are only available due to compatibility with older systems. |

|
Layer 3: DSCP signalling |
The values entered in the master are automatically transmitted to the satellites. A low class does not mean a lower prioritization. For FoIP (T.38) the configuration for DSCP class voice is used. Further information on the Layer-3 settings can be found via the hyperlinks in the section See also... |
